The End of The World With You (US adaptation)

Ethan Matthews lives a very boring, routine life. His life is spent working at a dead end job as a call center agent, watching shows online or playing Games on his phone. When news of a massive meteor hitting Earth in ten days time that will wipe out all life on the planet, Ethan makes peace with his own fate and decides to spend his final days reading books in the library. It is there that he meets Riley Kramer. The man who broke Ethan's heart many years ago back in college. With the world heading towards its end, Riley hopes to win back the one who got away and redeem himself in the process, while Ethan tries to move past his pain and trauma and find the one thing he's been missing out in life, a connection with someone else.

This is adapted from the manga series and Japanese Drama series of the same name. I do not own the rights to either series.
